What are the symptoms of respiratory acidosis?

A.

Headache and tremors

B.

Trousseau's and Chvostek's signs

C.

Crackles and rhonchi upon auscultation

D.

Hyperactivity and reduced serum ionized calcium levels

Answer and Explanation

The Correct Answer is A

A. Headache and tremors:

Respiratory acidosis leads to CO₂ retention, causing cerebral vasodilation, resulting in headache and neuromuscular irritability like tremors.

B. Trousseau's and Chvostek's signs:

These are signs of hypocalcemia, commonly seen in respiratory alkalosis, not acidosis.

C. Crackles and rhonchi upon auscultation:

These are lung sounds that might be present in respiratory conditions (like pneumonia or CHF) but are not specific symptoms of acid-base disturbances like respiratory acidosis.

D. Hyperactivity and reduced serum ionized calcium levels:

These findings are consistent with respiratory alkalosis, not acidosis.

Correct Answer is C

Explanation

A. It is the process by which a substance requires energy to pass through a membrane against a concentration gradient:

This describes active transport, not diffusion. Active transport requires ATP to move substances against their gradient.

B. It is the process by which solvent molecules pass through a semipermeable membrane from a less concentrated solution into a more concentrated one:

This describes osmosis, not diffusion. Osmosis specifically refers to the movement of water.

C. It is the process by which molecules move from high-concentration areas to low-concentration areas:

This correctly defines diffusion - the passive movement of molecules down their concentration gradient.

D. It is the process by which certain molecules pass through the plasma membrane with the help of carrier proteins:

This describes facilitated diffusion, which still moves substances down their gradient but requires a protein carrier.

Correct Answer is C

Explanation

A. A general low count of red blood cells:

This describes anemia, not hyperlipidemia.

B. Bulging or dilation of a portion of an arterial wall:

This describes an aneurysm, not hyperlipidemia.

C. Elevated levels of lipids in the bloodstream:

Hyperlipidemia means high blood levels of lipids (such as cholesterol and triglycerides).

D. A lack of red blood cell membrane proteins:

This is a description of certain types of hemolytic anemia, not hyperlipidemia.
